Abstract: This invention relates to a fire hydrant locating system which includes a hydrant locator that facilitates the location of a hydrant by firefighters, particularly in an emergency vehicle such as a fire engine. The hydrant locator as secured to the hydrant cylinder has a low profile. The hydrant locating system includes a transmitter adapted to be located in the emergency vehicle. Upon actuation of a switch in the transmitter in the emergency vehicle a receiver-signal generator in the hydrant locator will be activated to set off strobe lights to alert firefighters of the hydrant location. The receiver-signal generator in the hydrant locator includes a strobe light structure. The transmitter can be set such that when actuated it will activate only those hydrant locators within a preselected range such as approximately 1500 feet.

Abstract: A quick-disconnect fluid coupling is provided that includes a spout assembly comprising a spout fitment having a first fluid opening and a spout valve member having a second fluid opening and capable of rotating from a first position to a second position to form a spout fluid path between the first and second fluid openings. The fluid coupling also includes a service-line connector comprising a line fitment member including a third fluid opening, and a connector valve member having a fourth fluid opening and capable of rotating from a third position to a fourth position to form a connector fluid path between the third and fourth fluid openings, whereby a spout-connector fluid path is formed between the second and fourth fluid openings upon attachment of the service-line connector to the spout assembly.
